fastivab6tg25mr, I might try changing from "Corrected" to "Normal correction" and see if that helps. Otherwise, the only solution I can think of for an MS1 would be to switch "CLT-related density", use IAT, over-ride the RPM taper, and enter a map which is inverse of the normal correction map at half-scale. |

What about doing in hardware what you can't do in software? Use a space MS output to trigger a circuit to switch from an ambient air sensor to an in-intake sensor?
I had two AIT sensors at one point. The second under the driver side fender, with a little computer fan blowing on it. I'd use a relay with some RPM + TIME? (I can't rember) to trigger from one to the other. doesn't really help, still gets hot under the hood...the issue is the aggressive code that pulls way too much fuel at any temp abouve 85°F

thanks so much. i guess i just confused myself looking for something that wasnt there.

This is what I'm talking about. Air Density table switch to AIT, with the start/end correction RPM points set to like 2500 and 3000 respectively.
same function as the MAT corrections table in MSII and MSII. Us old-schoolers don't have none of this hoity-toity percentage scaling. :D |
ohhh. yeah well that part is trivial. I want the decay.

finally got around to putting in my 1000s from five0 so im setting up my corrections and i can't seem to get the CLT gauge to chane to the MAT even after i went into the .ini and changed it.
do i have to reload the firmware or something? |
:td: MSI
|
but its all that i have :'(
|
does anyone have an idea of what im doing wrong? do i have to reload the firmware in order for the clt corrections to turn into mat corrections? i was trying to use the lil green ball as a reference like the box says but it is still following clt values instead of the mat values i set it to.
|
and it's set to AIT under advanced? the green line should be following whatever that is set to, regardless of what the gauge displaying in that window shows.
|
its set to IAT but its following CLT thats why im so confused. any ideas?
|
MS1 user here. I was able to remedy the hot starting lean condition using the coolant related air density table adjustments table and it's working pretty good now. Thanks for that help.
Question- When constantly in boost at the track on a very hot day in Miami, my AFRs were getting leaner in boost, presumably due to high AITs. Is the MS1 pulling fuel due to high AITs just like on hot starts? Can I compensate for or prevent this? |
well on the MSI you have a decay to turn off the CLT-Based corrections after X rpm, probably set around 2500RPM, so the MS starts pulling fuel again based on the MAT. you may want to increase that value a little.

FWIW, my car was pretty dialed in with autotune to run 12.2 AFRs at 140kpa and 11.5 at 170kpa between 4000-7000RPM.
And I was reading about 13.4 AFR at 6-7psi in the same RPM range on the hot track with AIT's above 105*F. Too much difference when AIT's go up. |

I had that problem - and tried to change it to MAT correction, but it was still reading from clt temp. Had to go into the .ini file and change the line:
[CurveEditor] curve = clt_IATCorrC, "Coolant corrected Air Density, see Settings", 9 topicHelp = airdenHelp columnLabel = "Temp", "Offset" xBins = IATCTemp, mat <==change this, previously 'clt' yBins = IATCorS gauge = matGauge <== also change to this if it doesn't say this already Hope this helps! |

Just tried the above, found the curve editor in C:\Program Files\EFIAnalytics\TunerStudioMS_beta\config\ecuDe f\MSExtra format hr_10.ini manged to save it but the iat correction table is still showing coolant corrected. What am i doing wrong? Surely it should be iat corrected?

Sorry, I should have clarified: You need to change it in your project ini file, not the firmware ini file. Look for the mainController.ini file in the "projectCfg" folder.

All i need to do now is work out what offsets to use & all will be great again in my eunos world. thanks guys. Rob |
